39-year-old Knoxville resident Steven Dean McGinnis, who was found guilty of murder in the first degree in September, was sentenced to life in prison Tuesday at the Marion County Courthouse. The courts also overruled a motion by McGinnis’s lawyers for a new trial. McGinnis, who was found guilty of murder in the 2008 shooting death of Knoxville resident Robert Ohl, was also ordered to pay $150,000 restitution to Ohl’s heirs, among other orders.
